Abstract (en)
[origin: WO9116023A1] A keratome for making arc-shaped incisions in a cornea in order to correct astigmatism. The keratome (3) comprises an external tubular support (4) within which a rotatable inner tubular body (6) carries at least one internal knife (82) which can project by a predetermined amount in relation to a reference surface (13) according to which the inner tubular support (4) rests on the cornea (2). Arc-shaped incisions having a predetermined angular position and length can thereby be made, and the support (4) and the body (6) include a device (108) for determining their relative angular position.
